吹气技术在列车减阻和防雪方面的应用研究

References 15-17 in the manuscript all studied the drag reduction effect of blowing on trains, proving that blowing can indeed be used for drag reduction, but there have been no experiments or papers on placing the blowing ports in the bogie compartment, as described in this article. Due to the lack of experimental conditions, the reduction of head resistance cannot be verified, although numerical methods can currently match experimental results. However, after careful consideration, this statement is too absolute and still requires certain experiments to support it. Combining with question 10, this article removes the resistance part and focuses on describing the anti-snow effect under blowing. For the drag reduction effect, a three-car model will be used in subsequent developments.
